Be it known that I, ALMON P. WRITING, a citizen of the United States, residing at Paterson, in the county of Passaic and State of New Jersey, have invented certain new and useful thereon, which form a part of this speciiication.

rIhis invention relates to automatic signalbell ringers, principally designed for locomotives and all places where a signal or fog bell is required on river, ocean, or harbor boats, and the application of the same to and for such purposes. v

The object of the invention is tocontrive a construction for automatically ringing the sig` nal-bell of a locomotive, after the fashion of the engineer or tireman, giving to the bell that peculiar swaying motion and cushioning the same at the end ofeach stroke,which has only been attained heretofore by manual exertion and application. y

A further object is to devise asimple,ccm

pact, economical,` and efficient constructionfor accomplishing the foregoing results, which will be more fully hereinafter set forth.

In the drawings, Figure l is a side View of a locomotive, having the lower portion broken away, provided with my improvement; Fig. 2, a side view of the gearing, on an enlarged scale; Fig. 3, an end detail view of the gearing; Fig. 4, a detail view of the rear end of the connecting-rod interposed between the bell and the power-driven lever, on an enlarged scale; Fig. 5, an end view of the connecting-rod having the cap removed, and Figs. 6 and 7 are modified forms.

The body A of the locomotive forms a support for the small engine B, the bell C, and the bell-ringing mechanism, composed, essentially, of the power driven or actuated lever D and the connecting or bell rod E. The lever D may be directly connected with the engine B by pitman b, as shown in Figs. 6 and 7; or a multiple gearing `may be interposed between the pitman b and the lever D, as shownv in Fig. l, composed of the pinion f, mounted securely upon the outer end of the shaft F, having the crank f upon its inner end, to which the pitman b is connected, and the gearwheel G, meshing with the pinion,and having a wrist-pin, g, which is adapted to t in the semicircular slot d in thelever D. Instead of the gearing, a disk, G', driven from the engine B by pitman b, having a Wrist-pin, g', fitted in the semicircular slot d of the lever D, may be employed, as shown in Fig. 6. To further lever may be bell-crank shaped, as shown by D2 in Fig. 7.

Theupper end of the power-driven lever is yieldingly united with `the outer end of the connecting or bell rod E, and the opposite end of the bell-rod is connected with the bell C in the usual and well-known manner. The outer end of the bell-rod is bifurcated, forming arms e e, which extend parallel with each other for aconsiderable distance, and have their ends united by the cap E', bolted thereto. Between these arms e e is located theV sliding box or head H, which is heldfrom lateral displace ment by the arms e', projecting inward from head. These flanges may be integral with or separate from the arms and attached thereto in any approved way. Coil-springs I, located on each side'of the head, are held in place by the flanges and cushion the thrust of the rod and the stroke of the bell at each movement.

The upper end of the power-driven lever D is pivotally connected with the sliding head, and the throw ot' the hell can begegulated by adjusting the connection between the lever and head, as will be readily understood.

In practice the engine is -set in motion in the usual Way, and through the means set forth imparts an oscillating movement to the lever D, which, through the bell-rod E, rings or tolls the bell C. The inertia of the bell at the end of each stroke is taken up by one or the other of the coil-springs I, which form a cushthe several joints. rIhelever D', with the semicircular slot d, is best adapted for the purpose. and by practical demonstration has been found to give the best results; hence is the prefer able form.

Having thus described my invention, what simplify the construction, the power-driven the sides of the arms e and embracing the ion and prevent undue wear and straining of I claim, and desire to secure by Letters Patent, 1s-

l. The co1nbination,with thebellandpowerdriven lever, of a yielding connection interposed between and positively connecting the bell and lever for cushioning the stroke of the bell, substantially as described.

2. The con1binat-ion,with the bell and powerdriven lever, of the bell-rod connected at one end with the bell, a sliding head connected with the lever and located at the opposite end of the bell-rod, and the springs arranged on each side of the head for cushioning thestroke of the bell, substantially as set forth.

3. The combination, with the bell and the power-driven lever, of the bell-rod, the sliding head at one end thereof adjustably connected with the lever, and the springs on each side of the sliding head, substantially as described, and for the purpose specified.

4. The combination of the bell, the powerdriven lever, the bell-rod connected at one end with the bell and bifnrcated at the opposite end, forming arms which are flanged at their sides, the sliding head connected with the lcver placed between said arms and flanges, and the springs for cushioning the stroke of the bell, arranged on each side and held between the arms and. flanges, substantially as set forth.

5. The combination of the bell, the lever having a semicircular slot, the drivingcrank or wrist-pin tted in said slot for vibrating the lever, and t-he bell-rod interposed between and connecting the bell with the lever, substantially as specified.

6. The combination of the bell, the lever having a semicircular slot, the bell-rod yieldingly connecting the bell with the lever i'or cushioning the stroke of the bell, the crank tted in said seniicircular slot for vibrating the lever, and the supplemental steam-engine for driving the crank, substantially as described.

In testimony whereof I nfiix my signature in presence of two witnesses.
